This was for a job in London some years back. There was some damaged sections that needed replacing so I took down a section of the original moulding, cleaned the layers of distemper off, carefully coated it in Vaseline & then made a latex mould of it. Once i'd made a few, I lined them up side by side & made another mould so I could reproduce enough to do the job.
Hi Zigs your not just a pretty face then,well done my friend I want to be just like you when I grow up
Afraid not John, only visted the site once, made them back at the yard & then sent them up. Kept the moulds though, just as well, as the company went bust & never paid me my last months wages.
